whats x
1 answer:
Answer:
2x+4x-3+8x+18=43
We move all terms to the left:
2x+4x-3+8x+18-(43)=0
We add all the numbers together, and all the variables
14x-28=0
We move all terms containing x to the left, all other terms to the right
14x=28
x=28/14
x=2

G:$2.99
R:$16.99
For every 1R we have 3G.
1R+3G=$16.99+3($2.99)
So 1R+3G=$25.96
If we take $129.80÷$25.96, we get 5.

5R+15G=5($16.99)+15($2.99)
So 5R+15G=$129.80
